问题描述
我创建了一个简单的活动,我想从命令行开始并从命令行传递一些值。
I created a simple activity that I want to start from command line and pass in some value from command line.
但是,如果我尝试这样做
However, if I try to do
adb shell am start com.example.mike.app/.SimpleActivity --es "Message" "hello!"
然后接收活动中的消息, intent.getExtras()
返回null。
and then receive the message in activity, intent.getExtras()
returns null.
活动:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_activity);
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
Log.d(LOGTAG, intent == null ? "Intent is null" : "Intent is not null");
Log.d(LOGTAG, bundle == null ? "Bundle is null" : "Bundle is not null");
}
结果:
SimpleActivity(12345): Intent is not null
SimpleActivity(12345): Bundle is null
推荐答案
正确的命令应该是
adb shell am start -n com.example.mike.app/.SimpleActivity --es "Message" "hello!"
带有 -n
